Not sure if this is at all possible, but is there any way that, as soon as I start my application, that the title bar will change? So there is always a different title?
So, say my application title is called: Test Application: Instance 1, then ext time I load the application, the title will change to: Test Application: Instance 2, etc.
I am using Visual Studio Express 2015 for Windows Desktop.
I have just started this project, so has the default form load function:
namespace Application
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
}
}
This doesn't work = Form.load
I don't know what else to try or if it is at all possible.
So, I don't know if it is possible, because how do you know when to stop it counting? Or maybe only stop once it hits 10 application hits?
Basically, I want the same form, but a different title name.
Provide a handler for the Load event on your main form and set the Text property to the title you desire:
string newTitle = MethodWhichGeneratesTitleText();
this.Text = newTitle;
In this method you can check your database, config file or other sources that help you determine the title you need.

I am using the ReportViewer in my WPF application and I am trying to get a custom protocol to work with the application. So I get the ability to open sub-programs inside my application when a url is clicked inside the ReportViewer.
When I click on the custom-protocol-url (inside the ReportViewer) nothing happens.
When I open the same report via the Web-Browser, my URL works flawlessly.
It seems like the ReportViewer doesn't allow custom protocols? Has anyone experienced that aswell? Is there any documentation on that?
http, https and mailto are working in the ReportViewer.
I am just adding an Action in the Report pointing to my url
customurl://123
Url definition:
[HKEY_CLASSES_ROOT\customurl]
#="URL: customurl Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\customurl\shell]
[HKEY_CLASSES_ROOT\customurl\shell\open]
[HKEY_CLASSES_ROOT\customurl\shell\open\command]
#="\"C:\\Extra Programme\\TestAlert.exe\" \"%1\""
Testalert (just the test-program by microsoft):
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Alert.exe invoked with the following parameters.\r\n");
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
I have looked into the code of ReportViewer and found an if statement, that checks if the url starts with either http:// or https:// or mailto:.
It gets this information with Uri.UriSchemeHttp, Uri.UriSchemeHttps and Uri.UriSchemeMailto
So you could overwrite eg. Uri.UriSchemeHttp with "customurl" (if your url is customurl://123) before rendering the report.
var field = typeof(Uri).GetField("UriSchemeHttp");
field.SetValue(null, "customurl");
The more elegant solution would be, to use a webbrowser control and just show the SSRS Web-Page
Using .NET WPF and Windows 10, is there a way to push a local toast notification onto the action center using c#? I've only seen people making custom dialogs for that but there must be a way to do it through the os.
You can use a NotifyIcon from System.Windows.Forms namespace like this:
class Test
{
private readonly NotifyIcon _notifyIcon;
public Test()
{
_notifyIcon = new NotifyIcon();
// Extracts your app's icon and uses it as notify icon
_notifyIcon.Icon = Icon.ExtractAssociatedIcon(Assembly.GetExecutingAssembly().Location);
// Hides the icon when the notification is closed
_notifyIcon.BalloonTipClosed += (s, e) => _notifyIcon.Visible = false;
}
public void ShowNotification()
{
_notifyIcon.Visible = true;
// Shows a notification with specified message and title
_notifyIcon.ShowBalloonTip(3000, "Title", "Message", ToolTipIcon.Info);
}
}
This should work since .NET Framework 1.1. Refer to this MSDN page for parameters of ShowBalloonTip.
As I found out, the first parameter of ShowBalloonTip (in my example that would be 3000 milliseconds) is generously ignored. Comments are appreciated ;)
I know this is an old post but I thought this might help someone that stumbles on this as I did when attempting to get Toast Notifications to work on Win 10.
This seems to be good outline to follow -
Send a local toast notification from desktop C# apps
I used that link along with this great blog post- Pop a Toast Notification in WPF using Win 10 APIs
to get my WPF app working on Win10. This is a much better solution vs the "old school" notify icon because you can add buttons to complete specific actions within your toasts even after the notification has entered the action center.
Note- the first link mentions "If you are using WiX" but it's really a requirement. You must create and install your Wix setup project before you Toasts will work. As the appUserModelId for your app needs to be registered first. The second link does not mention this unless you read my comments within it.
TIP- Once your app is installed you can verify the AppUserModelId by running this command on the run line shell:appsfolder . Make sure you are in the details view, next click View , Choose Details and ensure AppUserModeId is checked. Compare your AppUserModelId against other installed apps.
Here's a snipit of code that I used. One thing two note here, I did not install the "Notifications library" mentioned in step 7 of the first link because I prefer to use the raw XML.
private const String APP_ID = "YourCompanyName.YourAppName";
public static void CreateToast()
{
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(
ToastTemplateType.ToastImageAndText02);
// Fill in the text elements
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
stringElements[0].AppendChild(toastXml.CreateTextNode("This is my title!!!!!!!!!!"));
stringElements[1].AppendChild(toastXml.CreateTextNode("This is my message!!!!!!!!!!!!"));
// Specify the absolute path to an image
string filePath = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86) + #"\Your Path To File\Your Image Name.png";
XmlNodeList imageElements = toastXml.GetElementsByTagName("image");
imageElements[0].Attributes.GetNamedItem("src").NodeValue = filePath;
// Change default audio if desired - ref - https://learn.microsoft.com/en-us/uwp/schemas/tiles/toastschema/element-audio
XmlElement audio = toastXml.CreateElement("audio");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Reminder");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.IM");
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Mail"); // sounds like default
//audio.SetAttribute("src", "ms-winsoundevent:Notification.Looping.Call7");
audio.SetAttribute("src", "ms-winsoundevent:Notification.Looping.Call2");
//audio.SetAttribute("loop", "false");
// Add the audio element
toastXml.DocumentElement.AppendChild(audio);
XmlElement actions = toastXml.CreateElement("actions");
toastXml.DocumentElement.AppendChild(actions);
// Create a simple button to display on the toast
XmlElement action = toastXml.CreateElement("action");
actions.AppendChild(action);
action.SetAttribute("content", "Show details");
action.SetAttribute("arguments", "viewdetails");
// Create the toast
ToastNotification toast = new ToastNotification(toastXml);
// Show the toast. Be sure to specify the AppUserModelId
// on your application's shortcut!
ToastNotificationManager.CreateToastNotifier(APP_ID).Show(toast);
}
UPDATE
This seems to be working fine on windows 10
https://msdn.microsoft.com/library/windows/apps/windows.ui.notifications.toastnotificationmanager.aspx
you will need to add these nugets
Install-Package WindowsAPICodePack-Core
Install-Package WindowsAPICodePack-Shell
Add reference to:
C:\Program Files (x86)\Windows Kits\8.1\References\CommonConfiguration\Neutral\Windows.winmd
And
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v4.5\System.Runtime.WindowsRuntime.dll
And use the following code:
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastImageAndText04);
// Fill in the text elements
XmlNodeList stringElements = toastXml.GetElementsByTagName("text");
for (int i = 0; i < stringElements.Length; i++)
{
stringElements[i].AppendChild(toastXml.CreateTextNode("Line " + i));
}
// Specify the absolute path to an image
string imagePath = "file:///" + Path.GetFullPath("toastImageAndText.png");
XmlNodeList imageElements = toastXml.GetElementsByTagName("image");
ToastNotification toast = new ToastNotification(toastXml);
ToastNotificationManager.CreateToastNotifier("Toast Sample").Show(toast);

I managed to gain access to the working API for windows 8 and 10 by referencing
Windows.winmd:
C:\Program Files (x86)\Windows Kits\8.0\References\CommonConfiguration\Neutral
This exposes Windows.UI.Notifications.
You can have a look at this post for creating a COM server that is needed in order to have notifications persisted in the AC with Win32 apps https://blogs.msdn.microsoft.com/tiles_and_toasts/2015/10/16/quickstart-handling-toast-activations-from-win32-apps-in-windows-10/.

I need to ebed a web browser in a Wpf app, I tried with the one from the toolbox but get some issues and went to CefSharp.
public MainWindow()
{
InitializeComponent();
BrowserSettings settings = new BrowserSettings();
Cef.Initialize(new CefSettings());
CefSharp.Wpf.ChromiumWebBrowser webBrowser = new CefSharp.Wpf.ChromiumWebBrowser();
licence_grid.Children.Add(webBrowser);
webBrowser.Address = "http://myurlToLoad the page";
}
The problem is when I used a normal url the page load.
But when I used the url I intend to use and whith which the user enter his user and password in a browser pop up (I mean not a pop up from the website) . I get an error with this page take yoo much time to load and nothing else.
Can someone give me some tracks to follow...
Thanks
It sounds like the popup you are referring to is in fact the site prompting for basic authentication.
In that case you need to provide an IRequestHandler.GetAuthCredentials handler.
As the question & answer is very old and i would like to give the latest update on this solution, there is slight change as per original solution suggested.
anybody consuming cefsharp need to implement the authentication dialog. and changes in method is
bool IRequestHandler.GetAuthCredentials(IWebBrowser browserControl, IBrowser browser, IFrame frame, bool isProxy,
string host, int port, string realm, string scheme, IAuthCallback callback)
{
//NOTE: If you do not wish to implement this method returning false is the default behaviour
// We also suggest you explicitly Dispose of the callback as it wraps an unmanaged resource.
// shyam - original implemenation.
//callback.Dispose();
//return false;
bool handled = false;
// Instantiate the dialog box
AuthDialog dlg = new AuthDialog(host); // create new dialog with username and password field.
// Open the dialog box modally
dlg.ShowDialog();
if (dlg.DialogResult == System.Windows.Forms.DialogResult.OK)
{
// The user did not cancel out of the dialog. Retrieve the username and password.
callback.Continue(dlg.UserName,dlg.Password);
handled = true;
}
return handled;
}
I have a page that is loaded into a frame. in the code behind, i have a string variable called mode. What i want to do is when a hyperlink is clicked, open the page and set the mode
I was hoping to do it declaratively. I tried doing
NavigatUri="myPage?mode=edit"
and then adding the following to the code behind after the initialize component call
mode = this.NavigationContext.QueryString["mode"];
But I was getting a page not found error. I have a feeling I'm on another planet. I'm new to silverlight. How do i navigate to a page in this fashion and pass that argument?
Take a look at the UriMapper in you main page. The final UriMapping would normally be the catch all that looks like this:-
<uriMapper:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/>
You will note the "/" at the beginning of the Uri and the corresponding page belongs in the "/Views" folder.
Use the attribute:-
NavigatUri="/myPage?mode=edit"
make sure your page in the Views folder.
However I'm pretty sure you already have that. Your real problem is your attempt to access the NavigationContext in the execution the page constructor. Its not available at that point in the pages lifecycle. You should not attempt to use it until OnNavigatedTo is executed.
public partial class MyPage : Page
{
public MyPage()
{
InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
string mode = null;
if (NavigationContext.QueryString.ContainsKey("mode"))
{
mode = NavigationContext.QueryString["mode"];
}
// Do stuff with mode.
}
}
The reason you are seeing "page not found error" is thats because the Nav apps ErrorWindow just assumes any failure to load a page was because it wasn't found. Which assuming you've coded your pages correctly is probably a reasonable assumption.
I'm building a custom control for Windows Phone 7+ that can do augmented reality image processing. The control works wonderfully in practice (when I run the app), but because I have the image processing running on a separate thread, it breaks when I try to open the page in Blend or the Visual Studio designer.
Here's an example of the thread I'm trying to run (basically taken from http://msdn.microsoft.com/en-us/library/hh202982(v=vs.92).aspx) :
public override void OnApplyTemplate()
{
// assigning template stuff, initializing my camera
_myManualResetEvent = new ManualResetEvent(true);
_myCameraProcessingThread = new System.Threading.Thread(ProcessingMethod);
_myCameraProcessingThread.Start();
}
void ProcessingMethod()
{
int[] myBuffer = new int[640 * 480];
while(_someCondition)
{
_myManualResetEvent.WaitOne();
_myCamera.GetPreviewBufferArgb32(myBuffer);
// do my processing stuff
_myManualResetEvent.Set();
}
}
This breaks the ever-loving heck out of Blend. Would love to know why.
It looks like you are doing a lot of run-time stuff in the OnApplyTemplate method.
This will get called when Blend or Visual Studio instantiates the design view of your control.
You should either check to see if you are in design mode using the DesignMode:
if (!DesignMode)
{
_myManualResetEvent = new ManualResetEvent(true);
_myCameraProcessingThread = new System.Threading.Thread(ProcessingMethod);
_myCameraProcessingThread.Start();
}
or move this code into a method/event handler that only gets called when the application actually runs.
